PLOW.

To all whom it may concern.- I

Be it known that I, SPENCER A. BARKER, a citizen of the United States, residing at Deport, in the county of Lamar and titat'e of Texas, have invented certain new and useful Improvements in Plows, of which the following is a specification, reference being had to the accompanying drawings.

The present invention relates broadly to new and useful improvements in plows and as its principal object aims to provide in connectio with a plow, an adjustable knife blade which is adapted to work in the rear of the plow share for cutting roots and the like and for steadying'the plow so that it may be easily guided.

A more specific object of the invention is to provide in connection with a plow, a cutter blade and to accompanying the cutter blade with adjusting means of such construction that a maximum range of adjustment is provided.

The above and other incidental objects of a similar nature, which will be hereinafter more specifically treated are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claims which are appended hereto, and form part of this application.

With reference to the drawings, wherein there has been illustrated the preferred em bodiment of this invention, as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure l is a side elevation showing the improveddevice; and Fig. 2 is a sectionalview on the line 22, of Fig. 1. i

As disclosed in the accompanying drawings, the improved device includes a plow beam 1, the rear end of which is curved downwardly to provide a standard 2. Bolted to each face of the standard at its lower end, are foot plates 3. A bolt lextends through the standard above the foot plates and to this bolt are pivotallyconnected the lower ends of a pair ofv handles 5. Pivotally secured to the. opposite faces of the beam are a pair of rearwardly extending brace rods 6, the rear ends of which are provided with a plurality of openings 7 adapted to receive bolts 8, which extend through openings in the handles and serve to adjustably connect the brace rods 6 and handles.

Application filed August 19,1914. Serial No. 857,547.

Pivotally secured at their forward ends,

foot plates and carry'between their adjacent faces, a knife blade 14., While I have shown two guide bars 13,,it is of course obviousthat only oneof these members need be employed, under some conditions. Pivotally connected to the rear ends of the guide bars, are the lower ends of a pair of brace bars 15. .The upper ends of these brace bars are provided with a plurality of openings 16, through which a rod or equivalent fastening device 17 is passed and engaged in the handles 5, whereby the knife bar may be raised or lowered to engage the knife different depths in the ground.

' I now desire to explain that the guidebetween the foot plates 3, are a pair of knife bars 13 which extend rearwardly from the be engaged in the ground can be controlled not aloneby the adjustment of the brace bars 15 .with respect to the handle 5, but also by theadjustment of the angle of inclination of the handles 5. Thus an unusually wide range of adjustment is possible with the present construction. Having thus fully described my invention, whatI desire to claim and secure by Letters Patent is 1. A plow including a beam, a standard, a knife blade, means pivo-tally connecting the blade adjacent to the lower end of the standard, handles pivotally connected to the standard above the pivot of the blade, an adjustable connection between the rear end of the blade and the handles, and an adjustable connection between the beam and the handles.

2. A plow including a beam, a standard, a pair of foot plates secured to the lower end of the standard on opposite sides thereof, a rearwardly extending vknife bar pivotally secured at its forward terminal between the foot plates, a knife blade secured to the bar,

handles pivotally connected to the standard whereby the angle between the knife bar above e pivot 0 th knife a Edie? th handlesm b ya ri dable connection between the bearn faind the testimony whereof I'hereunto affiX'my handles, brace members pivotally connected signatl lr'e'i'n' the presence of two Witnesses. at its lower end to the knife bar, at the rear SPENCER A.
